MEANS Fon ATTACHING TOP PIECES To HEELS Filed April 19, 1933 .Robert Bain 72am, Maw, l//fa/ ATTORNEYS Patented Feb. 27, 1934 I T E T FFCE Robert Bain, Collingwocd, Victoria, Australia Application April 19, 1933, Serial No. 666,905 In Australia January 12, 1933 3 Claims.

My invention relates to improved means for attaching top pieces to the heels of shoes and boots. The top piece of a heel is the rubber` or leather tread portion which comes in contact t with the ground. The object of my improvement is to enable the top pieces to be attached to shoes and boots in a readily renewable but secure manner. It is especially applicable to ladies shoes, where the heels are usually relatively high and narrow and the area of the tread portion is small.

I attain these objects by means illustrated in the accompanying drawing, in which- Figure 1 is a vertical section through the heel ci a ladys shoe showing the device with the top piece in process of attachment.

Figure 2 is a view similar to Figure 1 but showing the top piece attached.

Figure 3 is a section through the device showing the top piece in process or attachment.

Figure 4 is a View similar to Figure 3 but showing the top piece in the attached position.

Figure 5 is a sectional view of the device taken at right angles to Figure 4, and

Figure 6 is a sectional view of a modification of a detail.

A metal slideway 1 is adapted to be embedded in a hole 2 in the body of the heel 3. It will normally be held in position suiiiciently by a friction grip; but may be anchored in position by a cross pin 4, passed through the material of the heel and through holes in opposite walls of the slide- Way, as shown in dotted lines in Figure 1. An internally threaded metal socket member 5 is housed Within the slideway and is adapted to receive a threaded connecting member 6 by which the top piece '7 of the heel is attached. The member 6 may be mounted on a flat plate 8 adapted to be fastened to the underside of the 40 top piece by rivets 9. The socket member 5 is anchored in position within the slideway 1 by a return spring 10, one looped end 11 of which is secured by a pin 12 lying in grooves 13 in the end of the socket member. The other end 14 of the spring is also looped and is secured to the socket mem er 5 by a cross pin 15 one end of which projects beyond the socket member and slides in a bayonet slot 16 which is provided with a shoulder 17. The pin thus acts as a stop pin. When the top piece is to be attached, assuming that the spring is in the extended position with the stop pin 15 resting against the shoulder 17 of the bayonet slot, the threaded member 6 is inserted in the threaded bore of the socket member 5 and screwed home.

Locking pins 18,A

carried by the plate 8, are then almost touching the tip of the body of the heel. The top piece is then given a further partial turn to move the stop pin 15 away from the shoulder 17, so that the spring draws the pin down the bayonet slot 50 and the locking pins 18 of the top piece then pass into the material of the heel. This may be facilitated by previously forming small holes 19 therein. The top piece is thus locked in position. To replace a Worn top piece, it is drawn G5 out against the action of the spring and turned so that the stop pin 15 abuts against the shoulder 17 and, as the locking pins 18 then no longer engage the material of the heel, the plate 8 and top piece may be unscrewed and replaced.

Instead of mounting the threaded member 6 and locking pins 18 on a plate 8, they may be secured directly to the top piece as shown in Figure 6. The threaded member 6 may have a head 20 accommodated in a recess 21 in the top piece and may be clamped to the latter by a nut 22. Locking pins 18A may be driven through the material of the top piece.

I claim:

1. In means for attaching a top piece to a heel, a slideway secured in a recess in said heel, a bayonet slot in the Wall of said slideway, a threaded socket member slidable within said slideway, resilient means adapted to resist the outward movement of said socket member, a stop pin projecting from said socket member and adapted to move in said bayonet slot, a shoulder in said bayonet slot adapted to be engaged by said stop pin when said socket member is drawn out against the action of said resilient means and given a partial turn, a threaded connecting member fitted to; said top piece and adapted to engage said threaded socket member, locking pins connected to said top piece and adapted to pass into the material of the heel when said threaded connecting member has been driven home and said socket member turned to release said stop pin from said shoulder.

2. In means for attaching a top piece to a heel, a slideway secured in a recess in said heel, a bayonet slot in the wall of said slideway, a threaded 100 socket member slidable Within said slideway and anchored thereto by a return spring, a stop pin projecting from said socket member and adapted to move in said bayonet slot, a shoulder in said bayonet slot adapted to be engaged by said stop 105 pin when said socket member is drawn out against the action of said spring and given a partial turn, a plate adapted to be attached to the inner side of said top piece, a threaded connecting member mounted on said plate, said threaded connecting 110 member being adapted to engage said threaded socket member, locking pins projecting inwardly from said plate and adapted to be passed into the material of said heel when said threaded connecting member has been screwed home into said threaded socket member and said stop pin has been released from said shoulder.

3. In means for attaching a top piece to a heel, a slideway secured in a recess in said heel, a bayonet slot in the Wall of said slideway, a threaded socket member slidable Within said slideway and anchored thereto by a return spring, a stop pin projecting from said socket member and adapted 'memben locking pins driven through said top piece and adapted to pass into the material of the heel when said threaded member has been screwed home and said stop pin released from said shoulder.
